Circular dichroism is an essential spectral property for probing chirality. 2] An interesting effect arises when an achiral guest chromophore is complexed in a chiral host. The guest becomes optically active, a phenomenon referred to as ªinducedº circular dichroism (ICD). [3±5] The spectroscopic in

Under chemical ionization (CI) conditions, cis and trans 1,2-indanediols mainly react with the NH 3 /NH 4 + system via a nucleophilic substitution process. In the CI source several mechanisms can occur yielding the substituted [M + NH 4 -H 2 O] + ions at m/z 150. Collisionally activated reaction (CA
